Notes:

Phase-detect AF is available only on A7Rii and A7ii. On other Sony cameras, Contrast-detect AF with an EF mount lens may be inadequate for all but stationary or static subjects.

Even with the phase-detect AF on the A7Rii and A7ii, you may experience some "hunting" with longer telephoto lenses, with "autofocus performance progressively [deteriorating] as focal length gets longer."

On the A7Rii, the center AF points will always be the best.

Continuous AF is NOT SUPPORTED.

Eye AF is NOT SUPPORTED.

Autofocus accuracy depends heavily on the working condition of the lens. Lenses with hidden problems - which may not be apparent on Canon DSLRs- will lead to inaccurate and unreliable autofocus on your Sony NEX or Alpha camera.

There is no support for lens corrections, such as peripheral shading, CA, and/or distortion.

Some aftermarket battery grips may cause an erratic change in aperture while shooting.

Sony NEX cameras cannot display aperture values beyond f/1.0. If a f/1.2 Canon EF lens is used with the Speed Booster ULTRA, the resulting aperture is f/0.9, but the body displays the original aperture, f/1.2, to the body.

When the Speed Booster is used with the Sony A7 series, the body will turn on APS-C Capture mode. You cannot use a Speed Booster in Full-Frame Capture with a full-frame Sony Camera.
